Kainic acid (KA), is an analog of the excitotoxic neurotransmitter glutamate. Kainic acid induces seizures[1-3].
Kainic acid(200 µM; 45 min) exposure induced caspase and calpain activation in neuronal cultures[4]. Kainic acid(5 µM) induces seizure-like activity in cortical human neurons[5]. Treatments with KA(1-100 µM) resulted in a significant decrease in cell viability in primary cultures of hippocampal neurons [6].
KA-induced(10 mg/kg;i.p) excitotoxicity led to sustained hyperphosphorylation of tau in MAPT transgenic (Tg) mice. This can lead to memory deficits[7]. After 1.0 µg of Kainic acid was injected into the hippocampus of young mice at 6, 7 and 9 days of age, pyramidal cells died significantly [8]. Injection of Kainic acid(70 µl/min; 16 mg/kg;i.v) through the tail vein of a mouse reliably and rapidly induces status epilepticus (SE) which remits spontaneously and leads to the development of temporal lobe epilepsy (TLE) in a subset of mice[9].
